5 Claims.

This invention relates to window construction and more particularly to a type of window construction wherein the several elements of the sash, i. e., the glass pane and the lateral glassframing members, are supported within and sub stantially solely by a loop of cord passing under the glass and along its sides substantially in the plane of the glass, or by two cords (one along each side of the glass) secured together beneath the glass, the glass-framing members being shaped to receive both the cord and the edges of the glass.

One object of this invention is to provide a type of window construction wherein the glass pane is protected at its edges by framing members held in place without putty or the like by means of the cords Which support the sash.

Another object of this invention is to provide such a window construction wherein the glassframing members are so shaped as to serve simultaneously as a protection for the edge of the glass and as a flexible weather stripping between the sash and its frame.

Another object of this invention is to provide a window sash whose pane and glass'framing members are held in assembled relation, and supported by a loop of cord passing under the pane and along its sides, the sash being slidable in a window frame which has pivoted channel members allowing the sash to be swung from its normal plane of operation for cleaning.

- Other and further objects will appear in the course of the following description when taken with the accompanying drawings in which:

Fig. 1 shows in perspective a window construction embodying this invention;

Fig. 2 shows in vertical cross section a window construction embodying this invention taken along a plane through one pulley;

Fig. 3 shows in partial horizontal cross section the window construction of Fig. 1 along plane III-III with both sashes opened to an adjacent position;

Fig. 4 shows in vertical elevation an assembled window sash construction according to another form of this invention; 7

Fig. 5 is an exploded view of the parts which are shown in assembled relation in Fig. 4;

Fig. 6 is a partial vertical section illustrating another alternative embodiment of the window construction of Fig. 4;

Figs. 7 and 8 are partial horizontal cross sec tions showing alternative embodiments of this invention utilizing double pane sashes; and

- Fig. 9 is a partial horizontal cross section showing an alternative embodiment of this invention utilizing edge-sealed pairs of glass panes in each sash.

Whereas conventional window construction requires a four-sided sash secured at the corners, together with the necessity of securing the window pane therein by means of glazier points and putty or some other supporting means such as glazing beads, the present invention utilizes simple slip-on glass-framing members which are maintained in their proper position by a cord passing along the lateral edges of the sash and effectively supporting the weight thereof along the bottom of the sash thereby supporting the pane and its framing members as the sash is raised or lowered, and securing them in assembled relation. According to this invention, the

lateral glass-framing members may be made of resilient metal shaped in such manner that the member performs the dual function of receiving and protecting the edge of the glass in a relatively tight fit, and of serving as resilient weather stripping between the window and the lateral channeled window frame members in which it slides. The glass-framing member also affords an external continuous groove which retains in proper position the cord above-mentioned. This construction afiords the possibility of utilizing edge-sealed double panes of glass without using complicated and expensive frammg.

To facilitate cleaning the outer face 015 the lower sash, the lateral channeled window frame members are pivotally mounted, and divided in half with the two halves pivoted to each other, so that the entire sash may be swung into the room from its normal operating plane and conveniently secured in this position for washing while supported by its cords.

In Fig. l is shown a complete window assembly with the lower sash moved to its uppermost position and the upper part of the lateral window frame channels pulled inward to illustrate the manner in which the exterior face of the lower sash pane may be positioned for cleaning. As shown, the frame channels ID are each divided into two parts of about equal length and connected at the junction of these parts by hinges II. The upper end of the upper part of each frame channel is pivotally secured to window frame l2 and the lower end of the lower part is provided with a pin I 3 which slides in slot M. The lower and upper sashes may be joined by a continuous cord I5 which passes down each side of and beneath each sash and also over pulleys it, these pulleys being enclosed within housings II, but each sash may be otherwise counterbalanced if desired. The lateral glass-framing members it of the sashes are of metal construction which will. be discussed more fully in connection with Fig. 3, and the lower sash is provided at its bottom with a weather stripping 19, preferably of rubber, shown in cross sectional detail in Fig. 2. Nuts iii are utilized to secure locks 2! (Fig. 3) which extend through slots 22 to hold frame channels it in their normal position when the window is not being cleaned.

In Fig. 2, as shown, a cord i extends down each side of the sash and thence underneath the sash through a groove, and also passes over pulleys I6. Top and bottom members 39 and ill, respectively, or the inside sash are channeled as shown to permit the insertion of glass 32, and a suitable locking or clamping device 33 is provided at the top of upper member 35 to hold cord [5 securely in place. Top and bottom members 35 and 36, respectively, of the upper sash have similar channels for the insertion of its pane 32, and members 35 and 35 have a double tongue and groove interlocking construction as shown. including a weather stripping 3? which may also be of rubber. A locking or clamping device 33 is also provided at the top of top member 35 to secure cord l5. The upper part of channel id is pivoted at 38 to the fixed main frame of the window in such manner as to permit movement of the upper part of channel It to the position for cleaning as indicated by the dotted lines lila.

As shown in Fig. 3, the edges of the glass are received within channels formed in metal glassframing members 4% which may have a lateral margin reversely bent with respect to the channel to serve as a weather strip as well as to restrain and guide panes 32 at their lateral edges. Cords 15 are positioned within this reverselybent portion and serve to hold glass-framing member 43 tightly against the edge of the glass. Fig. 3 also shows the placement of pin iii in channel Iii so that it slides in slot i4 and the manner in which lock 2! extends through slot 22 and holds channel l3 firmly in its normal position.

As shown in Fig. 4, cord l5 may be divided into two sections whose ends are joined together beneath the bottom member 4! by a turnbuckle '12; or, as shown in Fig. 6, the two ends may be joined by reason of their common attachment to the bottom glass-framing member 4! by means of pins 43. Alternatively, cord l5 may be a continuous loop which passes down the side of the sash and along its bottom edge. Side members i and top and bottom members. 45 and ll, respectively, are grooved on their inner edges to permit insertion of the edge of the glass and are additionally grooved on their outer edges to allow the placement of cord l5 and turnbuckle 42 therein.

In Fig. 5 the components of 4 are shown in an exploded view in order to demonstrate the simplicity of construction and the ease with. which the window sash may be assembled or disassembled.

In Fig. 7 are shown upper and lower sashes each including two separate panes of glass 32. The edges of the two panes 32 are received and secured by parallel channels in the lateral glassframing members 48, the latter having on its opposite face a continuous longitudinal groove or channel adapted to receive the cord l5. Addi tionally, there maybe. provided a strip of re.-;

silient material As which fits into the groove and is held there by the cord, this strip having bent margins serving as weather stripping.

In Fig. 8 is illustrated an alternative construction for a double pane window sash in which a U-shaped weather strip member 50 is secured by welding or otherwise to one side of member 48, this U-shaped member also being shaped to provide an external slot in which cord I5 is positioned.

In Fig. 9 is shown window construction according to this invention utilizing double-pane sealed-edge glass, which characteristically has a continuous edge depression between the panes of glass. In this case the lateral glass-framing member 49 is shaped to provide on one face a continuous ridge which engages the depression between the panes of glass, and has curved proiecting portions serving as weather stripping. Thus the cord E5 fits within the channel which is the obverse of the ridge, and secures the frame against the glass.

When reference is made herein to a cord" it will be understood that the same may be rope, wire, chain or other suitable flexible material.
